Weight Plate
A weight plate is a flat disc loaded onto barbells, machines, and sleds to add resistance. In HYROX, plates load the competition sled for Sled Push and Sled Pull stations and are the fundamental unit of training load for all barbell exercises.
Definition
A weight plate is a flat, heavy disc designed to be loaded onto barbells, machines, and sleds to add resistance. Available in standard (25 mm hole) and Olympic (50 mm hole) sizes, weight plates are the fundamental unit of external loading in strength training. In HYROX®, weight plates load the competition sled for the Sled Push and Sled Pull stations and are used extensively in training to load barbells, leg presses, and plate-based exercises.
Specifications

| Cast iron | Iron, enamel coated | Varies by weight | +/- 3 % | General training |
| Calibrated competition | Steel | 45 cm (all weights) | +/- 10 g | Powerlifting, precision |
| Fractional plates | Steel/rubber | Small (various) | +/- 5 g | Microloading |

How It Is Used in HYROX®
Weight plates have two roles in HYROX®:
Competition: Plates load the competition sled to prescribed weights:
- Sled Push: 152 kg (men) / 102 kg (women) total
- Sled Pull: 103 kg (men) / 78 kg (women) total
Training: Plates are used on barbells, trap bars, and sleds for virtually every strength exercise in a HYROX® programme - squats, deadlifts, presses, lunges, and sled work. Bumper plates are preferred because they have a uniform 45 cm diameter, are safe to drop, and reduce floor damage.
Additional plate-based exercises for HYROX®:
- Plate carries - hold a plate at chest height and walk for core and grip endurance.
- Plate halos - circle a plate around the head for shoulder mobility.
- Plate front raises - build the anterior deltoid strength needed for Wall Balls.
Home Gym Alternatives
- Resistance bands - provide variable resistance without plates.
- Sandbags - fill bags to approximate plate weights for loading sleds or performing loaded exercises.
- Water containers - gallon jugs (~3.8 kg each) for light loading.
- Concrete plates (DIY) - moulded in a bucket for budget home gyms (fragile but functional).
HYROX® Context
Owning a set of Olympic bumper plates is essential for any serious home HYROX® training setup. A recommended starter set: 2 x 20 kg, 2 x 15 kg, 2 x 10 kg, 2 x 5 kg, 2 x 2.5 kg = 145 kg total. This covers barbell training and sled loading to approximate women's competition weight. For men's sled weight (152 kg), additional plates are needed. Bumper plates are preferred over cast iron because they protect floors, have consistent diameters, and allow safe drops during Olympic and power lifts.
FAQ
Bumper plates or cast iron - which should I buy? Bumper plates for a home gym. They protect floors, are safer if dropped, and have a standard 45 cm diameter that works for deadlifts from the correct height. Cast iron plates are cheaper but vary in diameter and can damage surfaces.
How many plates do I need for HYROX® training? A minimum of 100-150 kg in plates covers most training needs. For men's sled work at race weight, you need access to 150+ kg in plates plus the sled's base weight.
Are all weight plates the same size? No. Olympic plates have a 50 mm centre hole; standard plates have a 25 mm hole. Bumper plates are always 45 cm in outer diameter regardless of weight. Cast iron plates vary in diameter with weight. Ensure your plates match your bar type.
